Maxum, I've followed this forum for at least 10 years, and had to fix SLS on my TE (worn accumulators, one leaking strut, bad tandem pump). I'm certain no one here has posted about installing the air system you bought, or at benzworld dot org. Maybe you can search over at mbworld dot org, but I think you should have searched and read up about 124 chassis SLS before you bought the air mess.

Live and learn.
